Elevator for ptjddlers  balls



S. S. JACKMAN, 0F LOCK HAVEN, PENNSYLVANIA.

LEVATOR FOR PUDDLERS BALLS.

Specification of Letters Patent No. 14,242, dated February 12, 1856.

To all whom t may concern Be it known that I, SoLoN S. JACKMAN, of Lock Haven, in the county of Clinton and State of Pennsylvania, have invented certain new and useful Improvements in Elevators Adapted to Machines for Compressing Puddlers Balls; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

To enable others to make and use my improvement I will proceed to describe it as follows:

Figure 1 is an elevation, exhibiting the elevator attached to the side of a machine for compressing puddlers balls, such as I obtained by Letters Patent 31 July 1855, the elevator is extended to its full height and the receiving plate thereof raised to a position after having 'discharged its burden. Fig. 2 a side elevation of the elevator with the receiving plate at rest, and in a horizontal position. Fig. 3 a side view of the elevator at its full descent or lowest position.

This invention originally was designed for use in the connection with the compressing of puddlers balls: forming a portion of the application for Letters Patent above alluded to, as will appear by reference to said patent.

It consists of such an arrangement of de vices as will be hereafter described, so that by the tightening or drawing upon a cord or chain attached to the ends of a lever, it is caused to change its position, become elevated, carrying with it an upright stem or support which in all its changes shall maintain a perpendicular portion. To the upper end of said stem by suitable forks and hinges is connected a receiving plate at right angles to the stem, and in a horizontal position. On this plate the burden is placed. As for instance puddler balls of iron may lie on the plate, ring, or vessel, securely while raising, yet admit of the discharge of said mass at any desired height, simply by the tightening of a chain or cord, upsetting said receiving plate.

A A, is the framework of a'compressing machine. To the side thereof at a projection A is attached by suitable bolt (or pivot at lw) a lever P. From the lowerV side of this lever at its inner end, is a segment of a circle 3, whose center is coincident with the pivot w, and constitutes a pulley, admitting of an equal application of power, under the changes the lever may undergo.

g, is a brace or bar, placed parallel with lever P, they being so adjusted in their lengths that the distance between their pivots or attachments viz at fu, and 'w shall be equal. (Any deviation in their equal length may be rectified by ordinary means, such as a wedge and bridle, or otherwise.

1 is an upright supporter, forked at its upper end, or otherwise, to admit of the hinging of a plate, ring, or other vessel s, resting on said fork. They may be 3 or more in number. To a projection on the back of the ring, a chain 4C is attached, which is connected wit-h lever P at a suitable distance from the end of the lever, so that by tightening of this chain a change from a horizontal position is effected in the plate s. From the opposite end of lever P, drops a chain 5, which passes over the face of a pulley m', and across a second pulley m, placed at right angles thereto. The lower end of said chain may be connected to a windlasa. shaft or other power. The object to be raised is placed on plate s, when depressed as in position see Fig. 3, one end of lever P being then depressed by the drawing the chain 5. The other end raises the stem or supporter 7', perpendicularly, and with it the plate s, and its load. When suiiiciently elevated the check chain t on receiving its strain causes the tipping thereof and the load is delivered from the plate s. On the release of chain 5, the elevator descends by its weight, the stem therefore preserving its perpendicularity, and the plate s, returns to a horizontal position. There may be changes in the arrangement of these devices, in the adaptation to the various purposes to which it may be applied, and yet the principle be preserved.

Having described my improvement what I claim as my invention and desire to secure by Letters Patent, is-

The use of the pulley lever P, and brace g, in connection with the stem or supporter 1, and tilt plate s, constructed and operated substantially as described, for the purpose set forth.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
